Question

Balance the following equation:​

q) ${\text{HNO}}_3+{\text{H}}_2\text{S}\to {\text{NO}}_2+{\text{H}}_2\text{O}+\text{S}$

Answer 1

The skeletal equation is:

${\text{HNO}}_3+{\text{H}}_2\text{S}\to {\text{NO}}_2+{\text{H}}_2\text{O}+\text{S}$

• To equalize hydrogen, multiply ${\text{HNO}}_3$ and ${\text{H}}_2\text{O}$ by 2 .$2{\text{HNO}}_3+{\text{H}}_2\text{S}\to {\text{NO}}_2+2{\text{H}}_2\text{O}+\text{S}$
  
• To equalize nitrogen, multiply ${\text{NO}}_2$ by 2$2{\text{HNO}}_3+{\text{H}}_2\text{S}\to 2{\text{NO}}_2+2{\text{H}}_2\text{O}+\text{S}$

The equation is balanced.
